A platform bed, also known as a cabin bed, is a bed the base of which consists of a raised, level, usually rectangular horizontal solid frame, often with a section consisting of rows of flexible wooden slats or latticed structure meant to support just a mattress.

Trundle beds (or truckle beds, trumple beds or hurly-beds) are usually considered a pair of beds, one a twin bed, and the other slightly smaller on rollers or casters so that it may be put beneath the upper twin bed for storage.
